Description

一种防烫伤加热壶 技术领域
本实用新型涉及加热壶领域，具体是一种防烫伤加热壶。
背景技术
目前，现有的加热壶均由壶身和壶盖组成，在加热时会有水蒸汽排出，因此往往会在壶盖上开设排气孔，以便于水蒸汽的排出，但由于排气孔开在壶盖上，所以水蒸汽会垂直朝正上方排出，极易烫伤使用人。
实用新型内容
本实用新型的目的在于解决现有技术中存在的问题，提供一种防烫伤加热壶，它将水蒸汽从加热壶的斜上方排出，能够防止烫伤使用人，且水蒸汽能够在密封部的外壁上冷凝后回流至壶身内，能够减少水汽的排出。
本实用新型为实现上述目的，通过以下技术方案实现：
一种防烫伤加热壶，包括壶身、壶盖，所述壶身内的顶部设有支撑套体，所述支撑套体的直径自下而上逐步增大，且所述支撑套体的顶端与壶身固定连接，所述支撑套体的外壁与壶身的内壁之间留有间隙，所述支撑套体上设有排气孔，所述壶盖底部设有与支撑套体相适应的密封部，所述密封部的直径自下而上逐步增大，所述密封部的底端的直径小于支撑套体的顶端的内径，所述密封部的顶端的直径大于支撑套体的底端的内径；
且在将壶盖扣合在壶身上时，所述密封部的底端位于排气孔的顶端的下侧，所述密封部的外壁与支撑套体的内壁之间留有间隙。
优选的，所述密封部的顶端的直径大于支撑套体的顶端的内径。
优选的，所述密封部的外形呈双曲面状。
优选的，所述排气孔的数量至少为两个。
优选的，所述排气孔位于壶身的一侧。
对比现有技术，本实用新型的有益效果在于：
本实用新型将排气孔开设在壶身内的支撑套体上，壶身内的水蒸汽从排气孔排出后，碰撞到密封部的外表面反射出去，从而改变水蒸气的排出方向，将原有的正上方排出变为斜上方排出，能够防止烫伤使用人，且蒸汽能够在密封部的外壁上冷凝后能够经排气孔回流至壶身内，能够减少水汽的排出。
附图说明
附图1是本实用新型的结构示意图；
附图2是本实用新型的壶身的立体图；
附图3是壶身的内部结构示意图。
附图中标号：1、壶身；2、壶盖；3、支撑套体；4、排气孔；5、密封部。
具体实施方式
下面结合具体实施例，进一步阐述本实用新型。应理解，这些实施例仅用于说明本实用新型而不用于限制本实用新型的范围。此外应理解，在阅读了本实用新型讲授的内容之后，本领域技术人员可以对本实用新型作各种改动或修改，这些等价形式同样落于本申请所限定的范围。
实施例：如附图1-3所示，本实用新型所述是一种防烫伤加热壶，包括壶身1、壶盖2，所述壶身1内的顶部设有支撑套体3，所述支撑套体3的直径自下而上逐步增大，且所述支撑套体3的顶端与壶身1固定连接，支撑套体3与壶身1之间可采用一体式结构，所述支撑套体3的外壁与壶身1的内壁之间留有间隙，支撑套体3可采用外形呈圆台状的套体，支撑套体3的高度可根据壶身1的大小确定，一般不超过2cm。所述支撑套体3上设有排气孔4，排气孔4的数 量不限，可为一个也可为多个，优选为至少两个，且相邻两个排气孔4之间的距离不超过排气孔4的内径的两倍，能够快速排气。进一步的，所述排气孔4位于壶身1的一侧，在使用时，使用者站于远离排气孔4的一侧抓握壶身1上的把手，能够使排气位置远离使用者，进一步消除烫伤使用者的风险。所述壶盖2底部设有与支撑套体3相适应的密封部5，密封部5与壶盖2之间可采用一体式结构，也可采用卡扣连接或其它连接方式固定将密封部5固定在护盖2的底部，所述密封部5的直径自下而上逐步增大，密封部5的外形可采用下大上小圆台状，优选的，所述密封部5的外形呈双曲面状，能够加大密封部5的外表面的面积，为水蒸气的冷凝提供较大的附着面积，提高水蒸气冷凝效果。所述密封部5的底端的直径小于支撑套体3的顶端的内径，所述密封部5的顶端的直径大于支撑套体3的底端的内径，保证密封部5能够将支撑套体3的底端封闭，优选的，所述密封部5的顶端的直径大于支撑套体3的顶端的内径，能够将支撑套体3的顶端完全覆盖，将水蒸气的排除位置尽可能的远离使用者；
密封部5与支撑套体3的尺寸应保证，在将壶盖2扣合在壶身1上时，所述密封部5的底端位于排气孔4的顶端的下侧，所述密封部5的外壁与支撑套体3的内壁之间留有间隙，如下实施方式均可，密封部5的底端的外径与支撑套体3的底端的内径相同，密封部5的底端的外径略大于支撑套体3的底端的内径，密封部5的底端的外径略小于支撑套体3的底端的内径。
本实用新型将排气孔4开设在壶身1内的支撑套体3上，壶身1内的水蒸汽从排气孔4排出后，碰撞到密封部5的外表面反射出去，从而改变水蒸气的排出方向，将原有的正上方排出变为斜上方排出，能够防止烫伤使用人，且水蒸汽能够在密封部5的外壁上冷凝后能够再经排气孔4回流至壶身1内，能够减少水汽的排出，可广泛应用于电加热壶、烧水壶等。
